Description
In dem Hauptpatent ist gezeigt, wie man aus Endlauge der Kaliindustrie über das normale wasserhaltige Magnesiumkarbonat reines, sehr leichtes basisches Magnesiumkärbonat erhalten kann.In the main patent it is shown how to use the normal caustic solution from the potash industry hydrous magnesium carbonate pure, very light alkaline magnesium carbonate can get.
Es ist bekannt, daß man durch überschüssiges Ammoniumkarbonat aus Magnesiumsalzlösungen die Magnesia als Ammoniummagnesiumkarbonat ausscheiden kann. Es It is known that excess ammonium carbonate from magnesium salt solutions which magnesia can excrete as ammonium magnesium carbonate. It
*° hat sich nun gezeigt, daß sich an Stelle reiner Magnesiasalzlösungen auch Kaliendlauge verwenden läßt. Es werden ζ. B. zu 100 Teilen Ammoniumkarbonatlösung, welche in 100 cm3 14g NH3 und 20g CO2 enthält, 50 Teile Endlauge langsam unter Rühren zufließen gelassen. Ammoniummagnesiumkarbonat scheidet sich aus. Die erhaltene Doppelverbindung ist ein schwerer kristallinischer Niederschlag, welcher sich viel leichter von der MutterlaugeIt has now been shown that potassium hydroxide can also be used instead of pure magnesia salt solutions. There will be ζ. B. 100 parts of ammonium carbonate solution, which contains 14g of NH 3 and 20g of CO 2 in 100 cm 3 , 50 parts of final liquor allowed to slowly flow in with stirring. Ammonium magnesium carbonate is precipitated. The double compound obtained is a heavy crystalline precipitate which is much easier to separate from the mother liquor
ao trennen, läßt als das MgCO3 + 3 H2O.Separate ao, leaves as the MgCO 3 + 3 H 2 O.
Bei Verarbeitung von Kaliendlaüge erhält man jedoch kein reines Ammoniummagnesiumkarbonat, dasselbe ist vielmehr kali- und chlorhaltig. Diese Verunreinigungen könnenReceives when processing potash However, one does not use pure ammonium magnesium carbonate, rather the same is potassium and containing chlorine. These contaminants can
auch durch Waschen nicht entfernt werden, da sie nicht äußerlich anhaften, sondern; wahrscheinlich in isomorpher Form sich in den einzelnen ,Kristallen befinden. Man trennt den Niederschlag scharf von der Mutterlauge und deckt ihn mit etwas Fällungsflüssigkeit aus, dann rührt man ihn mit einer reichlichen Menge Wasser an und erhitzt langsam zum Ivqchen. Es spaltet sich zunächst Ammoniumkarbonat ab und schließlich, vor Erreichen der Kochtemperatur noch Kohlensäure. Man erhält eine reine, sehr leichte Magnesia alba, welche frei von Chlor- und Kaliverbindungen ist.cannot be removed even by washing, since they do not adhere externally, but; probably in isomorphic form in the individual, crystals are located. The precipitate is separated sharply from the mother liquor and cover it with a little precipitating liquid, then stir it with an abundant one Amount of water and slowly heated to quench. First ammonium carbonate splits from and finally, before reaching the boiling temperature, still carbonic acid. A pure, very light Magnesia alba is obtained, which is free from chlorine and Potash is.
Wenn es auch bekannt war, daß Ammoniummagnesiumkarbonat beim Kochen mit Wasser in ein basische"» Magnesiumkarbonat übergeht, so konnte doeh nicht vorausgesehen werden, daß ein aus Kaliendlaüge erzeugtes Produkt beim Kochen mit Wasser eine reine und sehr lockere Magnesia alba liefert, da die Erscheinungen, die beim Übergang des unlöslichen normalen Magnesiumkarbonats in basisches Magnesiumkarbonat auftreten, nicht mit einem Umkristallisieren im herkömmlichen Sinne verglichen werden können.Although it was also known to use ammonium magnesium carbonate in cooking Water changes into a basic magnesium carbonate, so this could not be foreseen be that one made from potash When boiled with water, the product produces a pure and very loose Magnesia alba, since the Phenomena that occur when the insoluble normal magnesium carbonate passes into basic magnesium carbonate do not occur with a recrystallization in the conventional Senses can be compared.
Von dem Verfahren der Schweizerischen Patentschrift 68191 unterscheidet sich das vorliegende \^erfahren fundamental dadurch, daß es die handelsübliche Magnesia alba liefert. Die Abscheidung der Magnesia wird auch nicht mit teilweise karbonisiertem Ammoniak, sondern mit Ammoniumkarbonat in bekannter Weise ausgeführt. Das erzeugte Ammoniummagnesiumkarbonat · ist ein sehr dichter Körper, weshalb man bei viel größerer Konzentration arbeiten und eine viel konzentriertere sa.lmialkhaltige Mutterlauge gewinnen kann.This differs from the method of Swiss patent specification 68191 The present experience is fundamentally due to the fact that it supplies the commercially available Magnesia alba. The deposition of the magnesia is also not carried out with partially carbonized ammonia, but carried out with ammonium carbonate in a known manner. That generated Ammonium magnesium carbonate is a very dense body, which is why it is much larger Work concentration and obtain a much more concentrated sa.lmialkhaltige mother liquor can.
